Title: Improvements in and relating to Coupling Means for Interconnecting Alternating Current Networks
Inventor: JONES KENNETH MEIRIG
IPC: H02H9/02
Filed: 1967-03-29
Abstract: 1,175,576. Tuned interconnectors for A.C. networks. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 25 June, 1968 [29 March, 1967], No. 14231/67. Heading H2H. An interconnecting arrangement between A.C. networks 1, 2 wherein an inductancecapacitance combination X1, XC is approximately series resonant when the networks are operating normally and which is detuned automatically when an excess current tends to flow in the interconnecting link due, for example, to a fault in one of the networks is provided with means whereby transient surge currents are suppressed and the return of the arrangement to normal stability assisted. When an excess current tends to flow in the interconnecting link the impedance of a path shunting the capacitor XC is considerably reduced by the alteration in the impedance of a non-linear element NL which is connected in series with two resistors R1, R2. Initially, when an excess current appears in the link the switch S, operated by a control unit C responsive to that current, remains open so that both resistors R1, R2 are effective to counteract any surge tendency in the link. After a predetermined time the unit C is effective to close the switch S whereby resistor R2 is short-circuited so stabilizing the operation of the network. After the fault has been cleared the unit C operates to open the switch S to re-insert resistor R2 into the shunt circuit whereby the return of the network to normal operation is expedited. The unit C may comprise an overcurrent relay with a built-in delay so that the switch S is closed after, say, three cycles of the excess current flow. The switch S may be of any suitable type such as a vacuum switch, a semi-conductor element or a therminonie device and may also be current directional. The non-linear element may comprise a saturable reactor or a linear reactor in series with a spark gap device, the spark gap comprising elements similar to the switch S. In another embodiment two capacitors are provided with the switch S in a connection between the point between the capacitors and the point between the resistors. In yet another embodiment the element NL is in series with one resistor only, the second resistor being in series with the switch S which combination is in shunt with X1 and XC.

Filed: 1919-06-10
Abstract: 150,824. Calverley, J. E., and Highfield, W. E. June 10, 1919. Commutator switching-arrangements; phase, changing.-In converting apparatus of the type in which a set of transformer windings are interconnected to form a closed circuit and connected to commutating-gear in substantially the same manner as that in which the winding of a Grammering armature is connected to its commutator, such as is described in Specification 140,853, two or more commutators are connected in series with one another through their 'brushes. In the arrangement shown in Fig. 1 for converting three-phase current to direct current, or vice versa, the closed circuit is divided into two sections A<2>, B<2>, each of which comprises a series of similar windings on the three-phase transformer cores A, B, and the sections are respectively connected to the segments C', D' of the commutators C, D. The transformer cores also carry windings A<1>, B<1> connected to three-phase mains X, Y, Z as shown in Fig. 2, in such a manner as to produce at successive commutator segments the relations shown in the phase diagram on the right of Fig. 2. The commutator brushes are mounted on a shaft E driven by a synchronous motor, which may be provided with means for adjusting its field strength or the angular position of the stator. The two commutators may be connected by an adjustable coupling K<3>, or the segments on one commutator may be adjusted angularly with respect to those on the other. The direct current output or supply is connected to slip-rings F, G. In cases where it is desirable to run the shaft at a reduced speed, the sections of the closed circuit may be connected to the commutator segments in such a manner as to give more than one possible brush position for each pair of brushes in substantially the manner adopted for multipolar direct-current machines. The number of commutators may be increased, each section of the closed winding being connected to two or more commutators in parallel, the sets of commutators being then connected in series.
